is particularly well adapted thereto.

A principal object is the replacement of the usual source of power in automatic devices, electric power, with the much less troublesome and 2 Claims. (01. lilo-50) ilarly shaped; secondary recesses or chambers l8 and 20, chambers l8 and i9 being opposed to,

costly source, the water pressure that is available at faucets in the home and elsewhere.

Another important object is the provision of a device for the purpose named that requires neither halving or other segmenting nor removal of the rind.

An additional object is a design that is equally adapted to single unit and plural unit devices.

Further objects are economy and simplicity of construction and maintenance and accessibility for quick and thorough cleaning.

This juicer comprises a lower or primary casing section II and an upper or secondary casing section I2, hingedly secured to one another by hinge assembly l3-l4 and lockable together by catch assembly l5-I6. a handle l1 being provided on section l2. Sections H and 12 are hollow, their walls being rigid and of metal, plastic or other suitable material, and referred to herein respectively as primary rigid wall and secondary rigid wall.

Primary section II contains the roughly hemispherically shaped, primary recesses or chambers i9 and. 2!. Secondary section l2 contains simportions 25b and rubber rings communicating with and adjacent one chambers 20 and 2| related.

another, being similarly disposed and Respectively disposed within chambers 19 and l8 and spaced from therespective defining surfaces 21 and 26 thereof by primary varying space 23 and secondary varying space 22, are primary hood 25, its primary flexible wall being indicated by 25a, and secondary hood 24, its secondary flexible wall being indicated by 24a,

Hoods 25 and 24 are adapted to collectively engage or embrace a fruit. The hoodsare separately and collectively referred to herein also as contractible fruit-engaging elements," the word elements appearing in forms.

The flexible rubberlike material, although they may be of impermeable, elastic or even suitably folded nonelastic cloth or other tion with impermeable rubber sheet.

material, such as thin The respective flanges or marginal '24b of hoods 25 and 24 are secured, by vulcanization or otherwise, to hard 29 and 28, which are threaded for screwing into annular portions Ha and I2a of sections II and I2 respectively, holes 29a and 28a being provided in rings 29 and 28 respectively to facilitate screwing of the rings into place with a suitable, special tool. Hood 24 is perforated to provide a hole for receiving therethru the screw 30 for screwing thereof into the top wall of secondary section l2, a washer 32intervening be-, tween the head of said screw and said hood.

symmetrically of secondary hood 24, it is provided with a hole for receiving flanged bushing 3|, held in place by nut 33, the function thereof being to fix hood 25 thereat to the rigid wall of section II in a watertight manner. Bushing 3| accommodates frictionally therein retained, flanged juice tube 35, pushed downwardly upon inserting the fruit into the device, by flange 3511. At its fruit-adjoining end, tube 35 is provided with serrations 35b, and. along the length thereof. with holes 350,

. respectively to facilitate the penetration of the fruit and the ejection of its juice.

Hinge assembly l3--l4 comprises secondary, hol ow hinge lug l4, extending from and preferably integral with secondary casing section l2 and provided with a thereto operatively fixed and therewith preferably the singular and plural walls are preferably of rubber or flexible substance, or the walls may be of permeable material in combinaprevented from being integral hollow hinge pin are inlet passage strikes attenuated part I eating continuously with one another. Assembly l3|4 also comprises primary hinge lug l3, extending from and preferably integral with primary casing section II and adapted to receive, rotatably, snugly, fitted therein, the hinge pin 36, into whose end a nut 33 is screwed for holding the two hinge lugs together, a washer thereat being indicated by 40, and a washer between the two lugs by 39.

Common to casing section II and to primary hinge lug l3, see Figures 3 and 5, is primary initial passage 4|, communicating continuously with primary varying space 23, see Figure 6, and, operatively alternately with the hollow interior 42 of hinge pin 36, see Figure 5. Also in lug l3,

which is preferably integral with lug l3, and outlet passage 41, see Figures 3 and 5.

In secondary hinge lug I4 is secondary, initial passage hollow interior 46 of lug l4 and with a secondary varying space that is not shown but indicated locally, see Figure 1, by numeral 48, and that corresponds in appearance and function to secondary varying space 22, see Figure 6. In the rigid wall of section I2 is secondary intermediate passage 34 intervening between and continuously communicating with spaces 43 and 22.

In the rigid wall of primary casing section II is primary intermediate. between and continuously communicating with space 23, see Figure 6, and with a primary varying space, not shown but indicated locally, see Figure 1, by numeral 49, and that corresponds in appearance and function to space 23.

Hinge pin 36 is provided, adjoining the cylindrical. interior surface of hinge lug l3, with first port 36a, second port 36b and third port 360, disposed in a manner whereby theyfunotion as valve elements. as will be apparent further on in this description.

For securing together the two hingedly connected members or casing sections II and I2, I provide a self-locking'lock or catch that requires no extra movement for locking otherthan simply closing section l2 downwardly quickly on to section ll This entirely novel catch assembly comprises a hook l6 that is operatively thereto fixed in section or member l2 and a lever I! that is rotatably mounted in section or member I I, see Figures 1, 2, 3 and particularly 4. The lever adjacent end "5a of hook I6 is recessed at l6b. Lever l5 comprises a pin portion lib and an arm portion l5a, the pin portion being recessed to constitute recess I50, adjoining attenuated part dv of pin portion lib. When section I2 is brought down quickly, lever-adjacent end l6a laterally thereof, whereby pin portion I5?) is rotated from the position in A to the position in B, where the normally downwardly extending, vertically disposed arm portion l5a has been swung up into a horizontally disposed position, see also D, a plan view of B. Gravity then exerts itself upon arm portion lia, whereby it swings downwardly again into said normal position, the attenuated part |5d then becoming engaged by the lever-adjacent end l6a at recess l'6b thereof, see C in Figure 4, the hook I 6 and the lever l5 thereupon being locked to one another and thereby locking casing sections H and I2 to one another. To disengage them from one another, the arm portion l5a is rotated upwardly to the position of Band D, the handle 43, common to inlet nozzle 45,

44, communicating continuously with not i'unctio 4 I1 is grasped and the section lifted away from section II.

When the sections are in open position, section l2 extending upwardly, a fruit, such as an orange, is forced down onto Juice tube 35 and is penetrated thereby. Section down and locked to section II in this relationship, port 36a establishes l2 may then be and when they are Figure 5, view A, shows that communication between passage and interior 42, port 36c establishes communication between interior 42 and inlet passage 43, and consequently with inlet nozzle 45, and port 36b is not functioning or is blocked. Also communication being continuous between interior 42 and passage 44, liquid, such as water under pressure entering through inlet. nozzle 45 passes into all four varying spaces thereby the four hoods are contracted, the fruit between them squeezed and the juice thereof ejected through the Juice tube.

When the sections are then opened, port 360 is see view B of Figure 5, port 36b has re-established communication between passage 4| and interior 42,

communication between interior 42 and outlet passage 41, and communication between interior passage 31 intervening powered by pressure fluid 42 and inlet nozzle has been blocked. Since communication between passage 44 and interior 42 is continuous, the fluid in the now upwardly extending section I2 is now free. under the force of gravity, to descend and leave the device by way 01' outlet passage 41. And, when the next fruit to be squeezed is introduced into primary chamber IS, the now contracted hood 2! is thereby distended and the fluid in the expanded space 23 is ejected through passage 4| and out through outlet passage 41.

Obviously a single unit device can be designed, wherein there are no intermediate passages such as 34 and 31 and wherein a passage like 44 leads directly from the upper or secondary lug into the secondary chamber corresponding to the primary chamber. that receives the fluid directly from the hinge assembly.

Also, obviously, with suitable modifications, a threeor four-unit ,device can be made, or one with even more, sothat quicker Juice-extracting can be effected.

Instead oi utilizing drinking or other water from the mains, any other fluid under pressure may be used, whether the fluid be a liquid or a gas, such as, for example, compressed air. 7

The word "fluid is used herein in its broadest sense to include liquids or gases.
